CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119(e) to U.S.Provisional Patent Application Ser. No. 62/844,761 entitled “METHODS ANDSYSTEMS FOR IMPROVED SIMULATION OF FIREARMS USAGE” filed in the name ofPackes, Jr. on Dec. 6, 2019, the entirety of which is incorporatedherein by reference.

TECHNICAL FIELD

This disclosure generally relates to firearms safety, and in particularit relates to safe practice with semi-automatic pistols.

BACKGROUND OF THE DISCLOSURE

Firearms are widely owned and used in modern society. Regarding pistols,semi-automatic actioned pistols and rifles have gained worldwidepopularity for their simplicity of use, reliability, and safety forvarious applications.

Virtually all owners of pistols and rifles including military, police,and citizens practice pistol and rifle techniques without liveammunition in order to gain proficiency in shooting fundamentals. Thisis commonly referred to as ‘dry-fire’ or similar, and is beneficial asit allows safe, highly available, and inexpensive opportunities topractice.

With common semi-automatic pistols specifically, dry-fire practice canbe inefficient in general, but more cumbersome based on action type:Single-action only (SAO), Double-action/Single action (DA/SA), or DoubleAction (DA).

For all semi-automatic pistols, dry fire practice lacks a reciprocatingslide. This portion of dry-fire practice is extremely important as itenables the shooter to re-acquire the sight picture after the slidemoves, disrupting the sight picture as firing a live round would. Acommon inconsistency in shooting which requires practice is re-acquiringsight picture after firing. Additionally, the lack of trigger reset ortrigger pull change without a reciprocating slide creates a disruptionto the shooter as they have to manually rack the slide rearward inbetween trigger presses.

In DA pistols such as the P250 manufactured by SIG SAUER INC., thetrigger can be pulled multiple times without resetting the action(commonly done by pulling back the slide as a live round would). Despitethe trigger being active and pressable multiple times without anyadditional user activity, the lack of slide reciprocation diminishes theeffectiveness of live-fire practice.

In DA/SA pistols such as the P226 manufactured by SIG SAUER INC., theuser will be able to pull the trigger multiple times, however thetrigger pull is not realistic. In DA/SA action the first trigger pullreciprocates then releases the hammer as in DA actions, howeversubsequent trigger pulls are SAO with a much shorter trigger travel. Dryfire practice without a reciprocating slide to reset the hammer andchange the trigger pull, as well as lack of a sight picture disruptionis inefficient.

SA or SAO pistols such as the GLOCK 19 manufactured by GLOCK INC as wellas many others are far more difficult and inefficient to use for dryfire practice, despite being the most popular actions in modern pistols.For a user to practice dry-fire, the user must manually pull back theslide to reset the trigger, pull the trigger, then once again pull backthe slide manually to reset the trigger and continue practice. Thisprocess greatly diminishes the value of dry fire practice as it is notrealistic or efficient.

Accordingly, there is a need for a method and apparatus to improveefficiency of dry-fire practice and allow semi-automatic firearms to,subsequent to a press of a trigger, reciprocate a slide to reset atrigger in order to make dry fire practice more effective and realistic,and remove necessary manual intervention.

SUMMARY OF THE DISCLOSURE

The present invention describes a Reciprocating Slide Device(s) (RSD)that can be used with a semi-automatic pistol or rifle, which will atleast partially reciprocate a slide or action enough to reset a trigger,upon user activation of the trigger. User activation of the triggerpushes a firing pin of the firearm action into a button of the RSD, viaeither hammer strike (DA/SA, DA) or striker release or set and release(SA) as is well known to one of ordinary skill in the art, causing aportion of the RSD to push backwards against the slide or action andreset the trigger of the firearm. In another embodiment, the RSD has ashock sensor which detects the hammer strike or striker strike of thefirearm and similarly causes a portion of the device to push backwardsagainst the slide or action of the firearm and reset the trigger. Inanother embodiment, the device of the present invention has a soundsensor in place of or in addition to a shock sensor to enable the abovefunctionality.

For use in a SA, DA, DA/SA or other action variant of a semi-automaticpistol, one embodiment of the present invention includes a ThreadedBarrel Rod Housing pushed into the muzzle end of the barrel of thepistol which includes a Barrel Rod Stop at the muzzle end, which threadsonto a Receiving Capsule fitting into the entry portion/chamber of thebarrel of the pistol. The Receiving Capsule may include a ReceivingCapsule Descending Support which aligns with the feed ramp of the barrelwhich further supports the Receiving Capsule, and also acts to depressthe follower of a standard pistol magazine (to prevent the slide fromlocking back when reciprocating due to the presence and proper functionof the follower on an empty magazine). The Receiving Capsule includes aReceiving Capsule Button aligned with the firing pin channel of thepistol, based on pistol caliber. When depressed by the firing pin, theReceiving Capsule Button of the Receiving Capsule activates anelectro-magnet housed either in the Receiving Capsule or in the BarrelRod Stop. The electro-magnet repels a Repelling Block, which may be asecond electromagnet, a magnetic substrate, rare-earth or standardmagnet, housed within the Receiving Capsule, Barrel Rod, or Barrel RodStop. When the Repelling Block is repelled by the electro magnet, theslide is pressed to the rear by the Receiving Capsule, Barrel Rod,Barrel Rod Block, Barrel Rod Stop, or a combination thereof to reset thetrigger. The Receiving Capsule, Barrel Rod, Barrel Rod Block and/orBarrel Rod Stop may include static or adjustable springs to furtherfacilitate slide reciprocation and augment the capabilities of theelectromagnet.

It is anticipated that within the apparatus, pressure adjustments may bemade by the user, or automatically by the apparatus. The user may havean analog (e.g. screw type adjustment) or digital (e.g. potentiometer)Pressure Adjustment Control (PAC) present on any one of the ReceivingCapsule, Barrel Rod, or Barrel Rod Stop in order to dial in correct andefficient/effective pressure needed to reciprocate the slide based onthe firearm type, guide rod spring weight, friction, or other factorswhich cause various pressures to reciprocate slides of varied pistols asis known by those in the art.

In another embodiment, a smaller version of the RSD is envisionedwhereby the functionality described above is encapsulated in a smallerunit, about the size of a standard cartridge suitable for use in eachfirearm. In this embodiment, the Barrel Rod and Barrel Rod Stop areshortened to fit within and be held backwards by the chamber of anymentioned firearm, for example, as the brass of the cartridge is held inposition and prevented from entering the barrel by the chamber offirearms.

Continuing from above, the use for semi-automatic rifles is similar. Forrifles such as the MINI-14 manufactured by RUGER, AK variants such asthose manufactured by CENTURY ARMS INC, AR-10 and AR-15 type variantssuch as the M&P Sport manufactured by SMITH AND WESSON, INC., theprocess and apparatus defined above is similar or identical. For rifles,for example, in the embodiment describing a full-length Barrel Rod, theBarrel Rod would be longer to accommodate generally longer barrels inrifles. Additionally, the functionality of the Barrel Rod and Barrel RodStop can be encapsulated within the bolt and bolt carrier group of therifle, reducing size of the apparatus. In other embodiments wherein theRSD is encapsulated at least substantially within the chamber of thebarrel of the firearm, the RSD would be smaller to fit within thechamber of the firearm barrel. These embodiments may use the bufferspring or other spring of the firearm against which to recoil.

As above, it is envisioned that in addition to or instead of anelectro-magnet, a Tension Adjustable Spring may be present to generaterearward force on the Barrel Rod or Barrel Rod Stop. The TensionAdjustable Spring would provide rearward force to assist theelectro-magnet, and could be adjustable using a Spring Adjustment knob,dial, switch, potentiometer or other mechanism or device able to changepressure in this manner. For example, a Spring Adjustment Knob on therear of the Receiving Capsule could be turned clockwise to tighten itrearward, inherently putting more rearward pressure on the spring. Sucha design would create flexibility for various designs of firearms andhelp offset the pressure of the firearm's guide rod spring, recoilspring, buffer spring, or any other spring or similar device used by thefirearm in actuating the action, assisting in loading of cartridges,etc. As a further example, a lower caliber pistol such as a .380 calibermay require less force to reciprocate the slide than a .45 caliberpistol. In this example, the user of the RSD would be able to loosen ortighten the pressure on the Tension Adjustable Spring to dial in a rangeof an amount of force for the RSD to operate properly. It iscontemplated that a guide for users would be provided, with indicationsof tension on the housing of the Receiving Capsule, or elsewhere on oroff the RSD, offering tensioning guidelines for various calibers andfirearm types.

DETAILED DESCRIPTION OF THE SPECIFIC EMBODIMENTS

FIG. 1 is an embodiment of the full barrel RSD in its collapsed state.The Barrel Rod Stop 11 attaches to the end of the Threaded Barrel RodHousing 12. This can be attached with threading on the inner and outerof the BRS and TBRH respectively, through a locking lug style system, orpermanently affixed. It is desired to keep the total length adjustablefor maximum compatibility with various barrel lengths, however that canalso be achieved with various sized buffers which can be affixed orattached between the BRS and TBRH to accommodate various barrel lengths.A goal in one embodiment is to ensure a tight fit between the BRS and/orBRS and buffer and barrel of the firearm. The TBRH is designed to sitinside the firearm barrel, providing a connection between the BRS andReceiving Capsule 10. An end user in one embodiment would feed the TBRHthrough the barrel of the firearm (e.g., a semi-automatic pistol withthe action open and/or slide locked to the rear). The end user wouldthen place the Receiving Capsule into the chamber of the barrel, thenscrew the TBRH into the RC. Lugs or other attachment means can be usedas long as the RC and TBRH are effectively connected. The end user wouldthen similarly affix the BRS to the TBRH to create a fit tight to themuzzle end of the barrel of the firearm. Upon closing the action, theRSD is ready to be used. The end user can insert a magazine as the RCDS13 will depress the follower of the magazine, preventing the followerfrom locking the firearm slide or action back. The end user can alsopractice magazine changes during practice with the RSD. The end user canthen, knowing fully well that the firearm is safe, press the trigger tothe rear activating the hammer or striker of the firearm, pushing thefiring pin forward. Upon the firing pin of the firearm striking the RCB14, the RSD mechanism (Described in detail below) pushes the Barrel RodBlock (15) backward against the slide or action of the firearm, causingin semi-auto pistols, for example, a sight picture disruption throughreciprocation of the slide of the firearm, as well as causing the hammeror striker and trigger to reset. This allows the end user to practicedry firing under the most realistic circumstances without actuallydischarging a round.

FIG. 2 is an embodiment of the full barrel RSD in its extended state.The BRB 15 has been pushed rearward to effectively take the firearm outof batter, reset the trigger as well as the hammer or striker. Afterextension, the BRB retracts back to its non-extended state, allowing thefirearm to return to battery with a reset trigger and hammer or striker.

FIG. 2a is a visual representation of one embodiment of how the fullbarrel RSD could fit inside of a standard semi-automatic pistol. As isevident by the illustration, the BRS 11 is protruding out of the frontof the firearm, providing options such as battery storage, tensionadjustment and more (described in detail below), as well as visuallyconfirming that the firearm is safe to dry fire. The BRS could becolored orange, for example, to confirm a safe firearm. Additionally,buffers can be used to ensure spacing is tight between the BRS and thefront of the barrel. The BRS and/or buffers would be covered in felt,plastic, vinyl, or created from same, to ensure no damage is done to thebarrel, muzzle, crown, or muzzle devices such as flash hiders or muzzlebrakes affixed the firearm. Further the BRS could be far smaller orshaped differently to accommodate existing holsters created for thefirearm. The TBRH 12 sits within the barrel of the firearm, and it isdesired to coat this in a rubber, felt, or plastic substance, or createor coat the TBRH in a way so as not to affect the bore of the firearm.For example, the TBRH could be a vinyl or rubber coated brass ormetallic rod. As illustrated, the RC 10 is placed in the chamber of thebarrel with the RCDS 13 descending into the magazine well of thefirearm. In other embodiments the RCDS is not present, however the RCDSprovides benefits including preventing magazine followers from affectingthe reciprocation of the action, providing more options for realisticpractice for the end user.

FIG. 3 is a cutaway showing inner parts of the full barrel RSD in itscollapsed state. In this embodiment, the BRS 11 houses springs,batteries, and a Laser Emitter/Battery Cap 34. The LEBC 34 can bepowered by the batteries of the RSD/BRS 11, and can be used with lasertraining devices such as those produced by LASERLYTE. Going left toright, the LEBC 34 can be removed to allow the end user to place one ormore batteries inside. In some cases, more battery power may benecessary based on the firearm model, slide weight, guide rod/recoilspring weight, and more factors. Further, in some embodiments, the LEBCalso acts as a tension adjustment cap, so that the end user can tightenor loosen the LEBC to adjust RSD system pressure in order to reciprocatethe firearm slide effectively. For example, if the RSD is not creatingenough force to reset the firearm action, the end user would be able totighten the pressure on one or more springs to add more power to the RSDand compensate for heavier recoil springs, or loosen pressure forlighter recoil springs. Additionally, the BRS 11 could have digitalpressure controls, such as a potentiometer or digital interface whichcan be adjusted by the end user to reduce or increase power to theElectro-Magnet 35. Continuing, upon activation of the RCB 14, the EM 35is activated, generating force against the Repelling Block 32. Thisforce plus spring(s) pressure is sufficient to push the BRB 15 rearwardto reciprocate the slide. It is desired that the RCB 14 is amomentary-type switch, so that upon press the RSD system activates for avery short period of time. After the BRB 15 is pushed rearward, thefirearm will go out of battery, reset the trigger and hammer or striker,then the lack of electromagnetic force will allow the recoil spring andaction of the firearm to return the RSD to its non-extended state. TheBlock Spring 31 provides additional force to help the EM 35 generateenough rearward motion to begin and/or continue opening the action ofthe firearm. This BS 31 can be adjustable using the LEBC 34, or otheradjustment mechanisms. The BS31 can also be present outside of the EM35and RB 32, as described below. The EM35, possibly combined with BS31 orother springs, creates electromagnetic force against the Repelling Block32 to carry out the function of the RSD. The RB 32 can also be a magnet,such as a rare-earth neodymium magnet to provide additional rearwardforce when the EM 35 is activated. Additionally, the TBRH 12 can beadjusted on either the RC 10 side or the BRS 11 side to ensure properfit, with or without buffers at the forward or rearward ends of the TBRH12 as pictured using Length and Tension Adjustment Threading 36. Ofcourse threading or other adjustment means can be used as describedherein, lugs, spacers, buffers etc.

FIG. 4 is an embodiment of the chamber-only RSD in its collapsed state.This embodiment aims to create a smaller overall RSD unit, eliminatingthe needs for the BRS 11, and TBRH 12. The BRS 11 and BRB 15 could beconsidered functionally the same part, for example. In this embodimentthe system is compacted to fit in the chamber of the barrel of thefirearm. The Battery Housing 30 presses against the forward portion ofthe chamber of the barrel in order to create a platform for rearwardpressure of the Barrel Rod Block 15. In another embodiment, the BH 30could be tapered outward to hold in place through pressure against thewalls of the barrel, for example, with an outwardly tapering reinforcedrubber wrapping or cap. The overall functionality of the RCB 14, BRB 15remain very similar to other embodiments as further described below.

FIG. 5 is an embodiment of the chamber-only RSD embodiment in itsexpanded state. Continuing from FIG. 4, the BRB 15 is extended in thisillustration, through the force of the spring(s) and EM 35.

FIG. 6 is a cutaway showing inner parts of the chamber-only RSDembodiment in its collapsed state. As with other embodiments, theoverall functionality of the parts represented function in a similarmanner. Similarly, the BH 30 can be used not only to house batteries,but also as an adjustment mechanism to increase pressure and assist theBRB 15 in moving rearward. Similarly, adjustments can be made to pressthe EM 35 and Repelling Block 32 closer together, increasing the forcegenerated by the EM 35 when activated.

FIG. 7 is a cutaway showing inner parts of the chamber-only RSDembodiment in its expanded state. As illustrated, the EM 35 combinedwith the BS 31 and RB 32 creates rearward pressure to force the BRB 15rearward and reciprocate the slide of the firearm.

FIG. 8 is a cutaway showing inner parts of an embodiment of thechamber-only RSD in its collapsed state showing one embodiment of theTension Adjustable Spring 81. In this embodiment the Block Spring 31 isreplaced with (or used in addition to) a TAS 81. The TAS 81 in thisembodiment is placed around the EM 35, and is placed against or affixedto the BHSA 80. Turning, or repositioning the BHSA increases rearwardpressure of the TAS 81 to increase the rearward power of the RSD,specifically the EM35 pressure against the BRB 15. For example, an enduser, upon installing, would be able to adjust the BHSA 80 to applyincreased pressure via the TAS 81 until the action of the firearm barelycloses. This would improve the performance of the EM 35 and RB 32 ingenerating rearward force as assisted by the TAS 81.

FIG. 8a is a visual of how the chamber-only RSD could fit inside of astandard semi-auto pistol. As illustrated the RSD unit fits within thebarrel chamber of the firearm, with the RCDS 13 descending along thefeed ramp of the firearm barrel.

FIG. 9 is a cutaway showing inner parts of an embodiment of thechamber-only RSD in its extended state showing one variant of theTension Adjustable Spring, It should further be evident that the BHSA 80can be tightened to increase spring pressure of the TAS 81, and/or topush the EM35 and RB 32 closer together to improve the efficiency of theEM 35 in creating rearward pressure. Again, as above, the goal ofadjustments along the RSD as a whole are to counter the various weightsof recoil springs in various firearms across manufacturers. It isenvisioned that a single RSD used by an end user would be able to workin many firearms with different barrel lengths, recoil spring pressures,action types (e.g. blowback vs. Browning), and more.

FIG. 10 illustrates an example battery compartment placement in oneembodiment of the RSD in its collapsed state. The system can be poweredby many types of batteries, button cells, rechargeable lithium ion, etc.The only restrictions are the power required for proper function of theEM 35 which should be evident to one of ordinary skill in the art, andbarrel size which affects BH 30 overall diameter.

FIG. 11 illustrates an example battery compartment placement in oneembodiment of the RSD in its expanded state.

FIG. 12 illustrates an embodiment of the RSD with an attached LaserEmitter. As mentioned above, a Laser Emitter/Battery Cap 34 can beincluded either affixed, or as an optional component so that the RSD canbe used with popular laser practice devices such as those offered byLASERLYTE, among others. The Laser Emitter could also be replaced with asmall white or IR light, or any other device capable of creating anemission readable but a secondary device, or perceptible by humansenses. It is anticipated that the Laser Emitter 34 would sit in frontof the RSD (toward the muzzle end of the barrel) and fit inside,oriented so that the Laser Emitter 34 produces results at least mostlyoriented with the bore so that activation achieves results consistentwith the sights of the firearm.

FIG. 13 illustrates a variant of the RSD for use in semi-automaticrifles, including a Laser Emitter. It should be apparent by theinformation herein that this embodiment is consistent with thecompact/chamber-only RSD, and a larger unit similar to FIG. 1-3 could ofcourse be used in this scenario. Regardless, in this embodiment theReceiving Capsule 10 is extended far enough to reach, nearly reach, orextend into a buffer tube of a standard semi-automatic rifle, such asthe M&P SPORT manufactured by SMITH & WESSON or any variant of theAR-15, AR-10, and similar rifles. Upon activation by the RCB 14 beingstruck by the hammer of the rifle, the Slotted Buffer Extension 130pushes rearward into the buffer tube of the rifle, against the bufferand buffer spring, thus resetting the hammer and creating a sightpicture disruption through at least partial recoil simulation and/oraction actuation. After the SBE 130 pushes rearward, the buffer springand buffer push forward against the SBE 130, returning the RSD to itsneutral position. Again, as above adjustments can be made via multiplecomponents as described herein to adjust for different buffer springtensions, buffer weights, trigger spring weights, and other factorsaffecting force required to reset the trigger and/or action on a rifleas known to one of ordinary skill in the art.

FIG. 13a is a visual of placement of one embodiment of the RSD within asemi-automatic rifle in its collapsed state. As can be seen in thisillustration, the RSD device in this semi-auto rifle variant is designedto replace the bolt and bolt carrier group of the rifle, furtherensuring safety during dry fire practice. The BH 30 can be slotted tomate with a standard AR type barrel such as those manufactured byBALLISTIC ADVANTAGE, or be smooth so as not to interact with the barrelgrooves or feed ramp(s) of the rifle. Similarly, the LaserEmitter/Battery Cap 34 can be oriented inside the barrel so thatactivation of the RSD activates the LE 34 for a duration of time longenough to be detected by popular target systems. In one embodimentglobally to all RSD variants, the LE can be attached and removed at thedesire of the end user, using screw-in type threading, magnets, lockinglugs, or other attachment means.

FIG. 13b is a visual of placement of one embedment of the RSD within asemi-automatic rifle in its expanded state. This illustration provides avisual of the RSD activation, specifically the Slotted Buffer Extension130 pushing rearward into the buffer tube and interacting with thebuffer and buffer spring of the rifle. The SBE 130 has a slot or cutouton the bottom to allow the hammer to pass inside of the SBE 130 andinteract with the Receiving Capsule Button 14 in order to activatefunctionality of the RSD. Further to the illustrations provided, someadditional functionality is contemplated as described below.

In one embodiment, the EM 35 could be reversed, so that when the MSR ison the EM 35 is attracting the Repelling Block 32, and upon activationof the Receiving Capsule Button 14, the EM 35 is momentarily turned offand the forces from the Block Spring 31 and/or TAS 81 drive the BarrelRod Block 15 and/or Slotted Buffer Extension 130 rearward.

In one embodiment, the Receiving Capsule Button 14 is not present,rather the RSD is activated upon impact using a impact detecting switch,motion detector, or similar on/off device which can be activated uponsudden impact. Of course, the RCB 14 may be present or not present, andfunction in conjunction with the impact detecting switch.

In one embodiment the RSD has an external power switch, in anotherembodiment the RSD turns on when the Barrel Rod Block 15 and/or SlottedBuffer Extension 130 is pushed forward/inward. When on, the RCB 14 isthen ‘listening’ for impact, upon which it performs the actionsdescribed above to activate the RSD. This embedment is useful forbattery conservation and end user safety.

In another embodiment the compact and full versions of the RSD asdescribed herein can be combined, so the end user has the option to havethe Barrel Rod Stop 11 protruding out of the muzzle end of the barrel,but can also use the RSD without it. This could be for user convenience,preference, or to include additional or larger batteries in the RSDunit. Also additional muzzle-end devices such as projectile launcherscould be affixed to the BRS 11 of the RSD.

In another embodiment, the EM 35 could be replaced with a motorizedscrew mechanism to create the reciprocation necessary to reciprocate theslide. For example, on actuation of the Receiving Capsule Button 14, themotorized screw mechanism would activate, the motor spinning for aduration necessary to create rearward pressure.

In various embodiments described herein the Threaded Barrel Rod Housing12 and Barrel Rod 33 could be combined, or supplemented with additionaliterations of bars/rods in order to add efficiency to the presentinvention. Further, threading for attachment could be moved to differentparts depending on implementation preferences, necessities,efficiencies, or other decisions regarding production. Threading ofcourse can be replaced with lug-style attachments, magnets, or any othermeans of fastening such items. In some embodiments attachments areunnecessary as the pressure created by installing the present inventionis sufficient to carry out the operation described herein.

Although the best methodologies have been particularly described in theforegoing disclosure, it is to be understood that such descriptions havebeen provided for purposes of illustration only, and that othervariations both in form and in detail can be made thereupon by thoseskilled in the art without departing from the spirit and scope thereof,which is defined first and foremost by the appended claims.
